content type for mp3 download response

Question

I have created a simple HTTP server which allows users to download files. But this does not seem to work for mp3 files. The content type currently is "application/misc". In order to make it work with mp3 files , I've tried "application/mp3" , "application/data" and "application/mpeg".

What would be the right content type for mp3 or audio file download, and am I missing some other headers?

---

EDIT: The file should automatically start downloading rather than prompting the user for saving it somewhere.

This question actually consists of two questions which were asked earlier: Which mime type should I use for mp3 and Forcing to download a file using PHP. As for save dialog, this is not under your control. – Irs

Answer 1

Try "Content-Type: audio/mpeg"

Update

To encourage the browser to download the mp3 rather then streaming, do

Content-Disposition: filename="music.mp3"'

Yeah I tried that too , but it starts streaming it. I want the file to get downloaded. – Arcanum

Are you setting more than 1 content type header? – Carlisle

As of now I m just using only one header i.e Content-Type. I guess Content-Disposition header would prompt user to save the file. I require the file to automatically start downloading. – Arcanum

My mp3 gets downloaded, but now it's zero KB. Any ideas? File on the server is 3MB so it should work? How does 'filename' find a file anyway? – Waly

The correct header for a download is Content-Disposition: attachment; filename="my-file.mp3" – Studding

Answer 2

.mp3    audio/mpeg3
.mp3    audio/x-mpeg-3
.mp3    video/mpeg
.mp3    video/x-mpeg

Using Content-Disposition: attachment... forces a download box to appear instead of having to right click -> save target as.

I've also seen audio/mpeg – Straightout

Answer 3

After a lot of research, I found some resources (some on SO) that led to this solution. It is the most cross device compatible solution out there and solves a lot of issues especially with Android devices (a lot of issues with them apparently).

Content-Disposition: attachment; filename="my_mp3_filename.MP3"

Take note of the upper-case extension. That is important.

Answer 4

Using Content-Type "application/force-download" worked for me.

Arcanum

The browser doesn't know how to display that content type inline, so the user has to download it (and decide what application is appropriate to play it). It'd be the same as doing: Content-Type: application/garbage – Scopolamine

Answer 5

try below content type it worked for me.

"audio/mpeg3;audio/x-mpeg-3;video/mpeg;video/x-mpeg;text/xml"
